Restructured a part of the skills database and how the Calculator interacts with them, reducing significantly the number of bugs in relation with the level requirement, points left to invest, synergies, and more.

Bugs

Added a link to Diablo Fans home page from the logo.

Fixed a bug with "Battle Command" and "Skill Shrine".

Fixed a bug with the "Next level" not displaying when it should in the tooltip.

Fixed the width of the extra skills inputs in the menu for Chrome browser.
